BACKGROUND Field of the Invention

The present invention relates to a chair which is suitable for general use, but particularly helpful for relieving the back stress and pain.

Description of the Related Art

Sitting in an office chair for prolonged periods of time can definitely cause low back pain or worsen an existing back problem. The main reason behind this is that sitting, in an office chair or in general, is a static posture that increases stress in the back, shoulders, arms, and legs, and in particular, can add large amounts of pressure to the back muscles and spinal discs.

When sitting in an office chair for a long period, the natural tendency for most people is to slouch over or slouch down in the chair, and this posture can overstretch the spinal ligaments and strain the discs and surrounding structures in the spine. Over time, incorrect sitting posture can damage spinal structures and contribute to or worsen back pain. There are multiple inventions that have been enlisted in prior art that are focused on reduction of back pain in an individual. For instance, a U.S. Pat. No. 4,709,963A issued to Jason Inc is an adjustable office chair (10) comprises a base assembly (12), a seat assembly (14) and a backrest assembly (16). The seat assembly (14) is horizontally rotatable on the base assembly (12) and is raised and lowered thereon by a manually controlled pneumatic actuator (24) connected between the base and seat assemblies (12, 14). The seat assembly (14) comprises a lower seat frame (50) which is mounted on the piston rod (28) of the pneumatic actuator (24) for horizontal rotation and an upper seat frame (52) which is mounted for vertical pivotal movement on the lower seat frame (50). A seat pan (54) is movably mounted on the upper seat frame (52) and is manually movable to selected attitudes wherein it is automatically releasably latched by a mechanism (56). The backrest assembly (16) comprises a lower backrest frame (120) and an upper backrest frame (122) which can be adjustably tilted relative to the lower backrest frame (120) and locked in a selected tilt position by a manually operable tilt lock mechanism (56). The backrest assembly (16) can be forced to a reclining position against spring bias of biasing springs (76) as the chair occupant leans backward and such backrest reclining motion is accompanied by proportional rearward and downward sloping motion of the upper seat frame (52) of the seat assembly (14). A manually adjustable linkage (94, 95, 100) adjusts the amount of spring biasing force acting on the upper seat frame (52) and on the backrest assembly (16) during such reclining motion. A manually controlled lockout mechanism (171, 172) selectively prevents or permits such reclining motion.

An office chair and adjustable lumbar support therefor bearing U.S. Pat. No. 5,902,011A is issued to U.S. Pat. No. 5,902,011A. The patent discloses an inflatable lumbar support system that includes a plurality of thermoplastic layers sealed together to form at least two laterally spaced bladders. A resiliently flexible face panel is disposed between the back of the user and the inflatable chambers. The panel is composed of form stable outer portions overlying the laterally spaced bladders and a medial portion therebetween of substantially greater yieldability than the outer portions of the panel. The inflatable lumbar support system is incorporated within a chair having a one-piece shell with a backrest that is cantilevered from the top of the backrest. The lumbar support system is carried by a mounting plate that includes a pair of mounting hooks that attach to and can slide vertically along the side edge of the cantilevered portion of the backrest. The lumbar support system can be slid vertically along the cantilevered backrest and can be inflated and deflated by a person setting in the chair.

A U.S. Pat. No. 6,955,402B2 issued to Herman Miller Inc is a fabric seat for a chair and a method and machine for manufacturing the fabric seat. The fabric seat comprises a seat frame that supports the outer circumference of a fabric material. The seat frame comprises grasping members that secure the fabric to the seat frame and retain the desired stretch in the fabric. The grasping members can be teeth. A cover is also provided, which is snapped onto the circumference of the seat frame, to trap the fabric and protect the user from the grasping members.

A sitting furniture, in particular swivel chair bearing U.S. Pat. No. 4,732,424A issued to Uredat Neuhoff Angela is a swivel-chair (10) has a frame (15) on which a seat (24) is movably mounted. A back (22) is connected with the seat (24), and this back (22) may be turned around a connecting point (19) at the frame (15). At this connecting point (19) a rotary spring (40) is provided, which tends to turn the back (22) into its working position, and the seat (24) is supported and guided at a seat-guide (31) at its forward area, that is where the thighs of the user are resting. This seat-guide (31) is preferably made such, that it will keep the inclination of the seat (24) on movement thereof, thus the so-called seat-slope, at an ergonomically advantageous value. A movement into the rest position goes against the rotary spring (40) and if required also the seat-guide (31) Optionally a blocking-device (45) for the seat (24) may also be provided in order to be able to block the seat (24) in any desired position in accordance with the wishes of the user.

An upright active-sitting seat bearing US Patent 2,013,030,6831A1 is an upright active-sitting seat provides a connection of a seating leg to a base through an articulating joint that allows the user to move a seat front to back and side to side, allowing a more active sitting that encourages blood circulation. The chair includes a seat supported by a post that is connected to a mount via a ball joint rod by a transverse rod that is routed through the ball joint rod end. By way of a coil spring that engages with the mount and the post, the post is spring biased to a home position relative to the mount. When using the chair, a person may move the seat from the home position to a comfortable seating position. When the person stands from the chair after using it, the chair returns to its spring biased home position.

An office chair having U.S. Pat. No. 6,688,690B2 issued to JSJ Seating Co Texas LP is a chair having an adjustable resilient back recliner mechanism, a pair of adjustable armrests, modular upper back portions and an adjustable lumbar support.
